Feel like quiting

In sch now and having lesson
I started to feel so tired and i don't want to do work anymore cause this lesson is so boring and the class is so big and have many students but only 1 teacher teaching! I need help but ppl also need help i call "teacher teacher" other ppl also call "teacher teacher" but she so slow then sometime call her ask her for help also no use cause she might now come to you...but need to call many many time then she come.
why can't this class have 2 or 3 teachers? so that i no need to wait.
i got so many things i don't know how to do and I don't feel like studing i feel like quiting sch i feel like doing other things but i don't even know what am i gd in. No one can help me, no one can help me.
I hope i can turn back the time and choose other course or anything
but i know its too late to regret, everything is too late i feel like crying cause there is so many things that i don't know how to do...
now waiting for her to come and help me but she still helping others and i've waited for quite long alrdy but she still haven come find me and help me
nabei.
I DON'T WANT STUDY ALRDY.
SICK AND TIRED OF EVERYTHINGS! LIFE SUCK, TEACHER SUCK NOTHING GD HAPPEN.
Living in hell
